Neonatal sepsis COMMONEST CAUSE OF NEONATAL DEATHS Source: Bang AT et al, Lancet 1999 NS-
Common organisms • Klebsiella pneumoniae • Escherichia coli • Staphylococcus aureus • Pseudomonas NS-
Symptoms of neonatal sepsis • CNS • Lethargy, refusal to suckle, limp, not arousable, poor or high pitched cry, irritable, seizures • CVS • Pallor, cyanosis, cold clammy skin • Respiratory • Tachypnea, apnea, grunt, retractions NS-
Symptoms of neonatal sepsis • GIT • Vomiting, diarrhea, abdominal distension • Hematological • Bleeding, jaundice • Skin • Rashes, purpura, pustules NS-
Signs of neonatal sepsis • Cold to touch ( hypothermia ) • Poor perfusion ( CRT ) • Hypotension • Renal failure • Sclerema • Bulging fontanels, neck retraction • Poor weight gain* * Indicates low grade sepsis NS-
Feeding ability reduced No spontaneous movement Temperature >380 C Prolonged capillary refill time Lower chest wall indrawing Resp. rate > 60/minute Grunting Cyanosis H/o of convulsions Clinical features of severe infectionsWHO Young Infant study 2003 NS-
Diagnosis of neonatal sepsis • Direct • Isolation of organisms from blood, CSF, urine is diagnostic • Indirect -Screening tests NS-
Sepsis screen • Leukopenia (TLC < 5000mm3) • Neutropenia (ANC < 1800/mm3) • Immature neutrophil to total neutrophil (I/T) ratio (> 0.2) • Micro-ESR (> 15mm 1st hour) • CRP +ve *If two or more tests are positive treat infant as neonatal sepsis NS-
Neutrophils Mature neutrophil Band cell NS-
Meningitis • 10-15 percent cases of sepsis have meningitis • Meningitis can be often missed clinically • LP must be done in all cases of late onset & symptomatic early onset sepsis NS-
Management: Supportive care • Keep the neonate warm • If sick, avoid enteral feed • Start IV fluids, infuse 10% dextrose- 2 ml/kg over 2-3 minutes to maintain normoglycemia • Maintain fluid and electrolyte balance and tissue perfusion. If CRT >3 sec, infuse 10 ml/kg normal saline NS-
Supportive care • Start oxygen by hood, if cyanosed or having RR >60/min or severe chest retractions • Consider exchange blood transfusion, if there is sclerema NS-
Choice of antibiotics + • Pneumonia or Sepsis Penicillin Aminoglycoside (Ampicillin or Cloxacillin) (Gentamicin or Amikacin) • Meningitis Ampicillin + Gentamicin Or Gentamicin or Amikacin + Cefotaxime NS-
Culture-ve Culture +ve Clinically not sepsis (Stop Ab) Clinically ill (Cont Abx7-10D) Meningitis, Osteomyelitis (Cont Ab X 3-6 wks) Pneumonia, Sepsis (Cont Ab X 7-10D) Suspected neonatal sepsis • Start parenteral antibiotics • Send cultures (report in 72 hrs) NS-
Superficial infections • Pustules - After puncturing, clean with betadine and apply local antimicrobial • Conjunctivitis - Chloramphenicol eye drops • Oral thrush - Local application of nystatin or Clotrimazole NS-
Prevention of infections • Exclusive breastfeeding • Keep cord dry • Hand washing by care givers • Hygiene of baby • No unnecessary interventions NS-
Six steps of hand washing Step 1 Wash palms with fingers Step 2 Wash back of hands Step 3 Wash fingers & knuckles Step 4 Wash thumbs Step 5 Wash finger tips Step 6 Wash wrists A scanned picture of steps of hand washing NS-
Hand washing • Simplest, most effective measure for preventing hospital acquired infections • 2 minutes hand washing prior to entering nursery • 15 seconds of hand washing before touching baby • Alcohol based hand rub effective but costly NS-
Control of hospital infections • Hand washing by all staff • Isolation of infectious patient • Use plenty of disposable items • Avoid overcrowding • Aseptic work culture • Infection surveillance NS-
Work culture • Sterile gowns and linen for babies • Hand washing by all • Regular cleaning of unit • No sharing of baby belongings • Dispose waste-products in separate bins NS-
Control of hospital outbreak of infections • Epidemiological investigation • Increased emphasis on hand washing • Reinforce all preventive measures • Review of protocols of nursery • Screen all personnel • Review of antibiotic policy • Cohorting of infants NS-
Fumigation • Use Potassium permanganate 70 gm with 170 ml of 40% formalin for 1000 cubic feet area for 8-24 hours alternatively Bacillocid spray for 1-2 hours may be equally effective NS-
Conclusion • High index of clinical suspicion • Look for lab evidence of sepsis • Start parenteral antibiotics (I.V.) Ampicillin + Aminoglycoside • Provide supportive care • Review culture reports • Practice barrier nursing to prevent cross-infection NS-
